# Convert a data structure and output it as YAML

# The data you want to convert to YAML
# @param options
# A hash of options that will be passed to Ruby's Psych library. Note, this could change between Puppet versions, but at time of writing these are `line_width`, `indentation`, and `canonical`.
#
# @example Output YAML to a file
# file { '/tmp/my.yaml':
# ensure => file,
# content => stdlib::to_yaml($myhash),
# }
# @example Use options to control the output format
# file { '/tmp/my.yaml':
# ensure => file,
# content => stdlib::to_yaml($myhash, {indentation => 4})
# }
#
# @return [String] The YAML document
